Application inea october 29, 1924. seriai No. 746,585.

To ZZ whomz't may concern.' i

Be it knownV that l, Jol-IN oi-mon, a citizen of the UnitedSta,tes,"residing at the city of Holyoke, in the county of Hampden and`State of Massachusetts, have invented certain new and usefulImprovements in Book Covers; and I do declare the followingV to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and usethesame.

This invention relates to book covers of the style shown and describedin my U. S. Letters Patent No. 1,512,489, issued October 21, 1924.

But this improvement has nothing whatever to do with any particularstyle of hinging whereby the covers are connected with the back of thebook, but relates solely to the flexible side covers that are so formedthat portions thereof will extend beyond either end of the hingedportion of the metallic back plate, the particular object being toprevent books of this sort from tearing the pockets or scratchingr thedesk.

Therefore in the following description no special mention will be madeof any particu.- lar form of complementary hinge elements that arecarried by the metal back and by the side covers, since the presentinvention applies to all books of this particular style, as identifiedby my Letters Patent above referred to, irrespective of the manner inwhich the hinge elements are formed and interconnected. Y

In the drawing Y Figure 1 is a view ofthe inside of the book cover withthe side covers fully opened- 'Figure 2 is a similar view of the outsideof the book cover with the sides fully opened- Figure 3 is a detail viewof one form of the liexible covers the latter being fully opened, and yFigure 4 is a fragmentary plan view of a slightly modified form of myinvention with the parts detached.

Similar numerals of reference denote like parts in the several figuresof the drawing.

1 is the metal back, having at its side edges complementary hingeelements 2, and 3 are the flexible side covers that are cut away so as`to form a recess or jog 4 at their inner portions, the length of this jog, which is the inner edge thereof, being equal to the length of thatportion of the metal back 1 which carrieshinge elements.

This inner edge carries hinge elements 6 that are complementary to theelements 2 and are interconnected therewith so as to form hingeconnections between the coversand the back plate 1. f

The formation of thejogs 4 leaves flaps 7 which are flexed toward eachother andV are secured together by any suitable clips 8, as clearlyshown in the drawings.

It will therefore be clear that I have provided flexible extensions ofthe cover that form a part of the back of the book so that there can beno danger of tearing pockets in which `the book might be placed or inmarring a desk when the books are manipulated thereon.

In the invention as heretofore described, and as particularly identifiedby the con# struction shown at Figures 1 and 2, the side covers are madein two halves or sections,

because it would be very expensive to form v these covers integral froma single piece of leather with the central portion cut away as at 5,shown at Figure 3, owing to the fact that considerable leather would benecessari-- ly wasted, and comparatively small pieces of leather couldnot be used at all, whereas if the covers are made in sections they canall be cut out of smaller pieces of leather with no appreciable waste.

But the invention is the same whether the cover is made in sections'orin one piece, and therefore is not limited in this respect.

Referring particularly to Figure 4 it will be observed that the metalback plate 1 has extensions 9 at each end which make this platesubstantially as long as the covers themselves, while the length of thatportion of kthe plate that carries the hinge elements 2 is substantiallythe same as the length of the jog in the covers as hereinbeforedescribed.

There is no particular object in extending the back plate in this`manner, yexcept to ico show that such extension is fully within thescope of the invention.

What is claimed is Y 1. A book @over comprising a back ,and side coversconnected thereto by hinge ele.-

nients, said cjoyersvhaying extensionportions at theirupper and lowerends .which extend inwardly toward each other and substantially parallelWith said back. l

2L A book eoyer comprising a nietal baek and side coverspconneoted"tosaid back Vby hinge ele1nents,the side covers having portions above andbelow said inetal back Whieh extend substantially parallel with saidbaek whereby flexible extensions are provided atv the back of the book.y A

` 3. book cover Comprising a metal back having alongits edges hingeelements, and flexible Side covers that are longerthan said back andareeut away at their inner por tions to forni recesses, fthe inner edges osaid recesses being of .substantially the saine length: as that of saidback andhavinghing'e elements seured thereto which Iare conneeted Withthe hinge elements of said back, said covers having portions that extendaorossthe back ofthe book in'n'nediately beyond both ends thereof.

.4. A book ycover comprising a metalbaol hai/'ing hinge elements. atitsside edges, and eparate flexible side covers that are longer thansaidback `and have jog-s out intheir -to therbaek, lthe kends of the coversbeing` Aflexed around at the back of' the book iininediately beyondtheends ofthe baekand secured together in: abutting relation.

:5. Abaek Cover comprising anietal back plate and cover portionshinged'to,saidlplate throughout Vthe rmiddleportion of their lengthitheends of theeoverszhaving extensionsthat` forni a part'of the back of thebook. f

In testimony whereof I amx my signature hereto. 'Y f JOI-IN SCHADE.
